BMI Calculator Using Python

In this blog, we will learn how to create a Body Mass Index(BMI) calculator using Python.

Before that, we need to understand the term Body Mass Index(BMI).

Understanding Body Mass Index

Body Mass Index (BMI) is the measurement of a person's height and weight. Generally, we use BMI to label a person's health by measuring their height and weight. There are four categories in labeling, such as underweight, healthy, overweight, and obese. Fitness trainers and doctors use this calculator to help promote healthy life and eating.

Understanding the Calculation

According to the above table, if a person's BMI is below 18.5, then that person is underweight. A Body Mass Index of between 18.5 and 24.9 is normal, and so on.

Creating the App

We will start by determining the height and weight of a person.

Now, let's calculate the BMI using a function named BMI and print it using a print statement.

We are getting the BMI number here. Let's check if the person is healthy, overweight, or obese. For that, we will use the condition expression from Python.

And now we have successfully made a BMI Calculator using Python.
